Research And Implementation Of Heterogeneous Data Conversion Based On XML Technologies

With the large number of information systems development and put into use, duing to the diversification of development platform and application system complexity, data sharing has become a major issue, which presents a heterogeneous data conversion problems between different systems.This thesis is based on the analysis of model-driven mapping, then combine the structural characteristics of heterogeneous data, firstly, by used XML files to represent the source and destination tables of structural information (S_XML) and value information(D_XML), designed a relational database, data conversion model. Then,by matching and mapping the source to target structure of the document operations the data exchange process.So, the semantic conflicts of heterogeneous data in structures, definitions and links are resolved, and eventually completed the data conversion.At last,used the model in the application of data exchange process in the postal agency system of Shaanxi Province, tested its justifiability and correctness.
